(b) When the latch interval is set to "Time Setting"
The processing time listed in the following table is required. The scan time including the first END processing
after a preset time has elapsed increases.
Q03UDVCPU, Q04UDVCPU, Q06UDVCPU, Q13UDVCPU, Q26UDVCPU
To reduce the scan time increase due to latch
latch relay) as much as possible by performing the following.
• Move data to be latched to the file register.
• Store device data that is less frequently updated in the standard ROM with the SP.DEVST instruction. (The device
data stored in the standard ROM can be read with the S(P).DEVLD instruction. (
• Set the latch interval to "Time Setting". (
*1 For file registers (including an extended data register (D) and an extended link register (W)), the scan time is not
increased due to latch.

Service processing time
Service processing is the communication processing with a programming tool and external devices. When
monitoring device data, reading programs, and setting monitor conditions in a programming tool, the processing
time listed in the following table is required.
